|
|
* - defaultExtension adds the extension only if the exact extension is not present
|
|
* - defaultJSExtensions applies after map when defaultExtension is not set
|
|
* - if a meta value is available for a module, map and defaultExtension are skipped
|
|
* - like global map, package map also applies to subpaths (sizzle/x, ./vendor/another/sub)
|
|
* - condition module map is '@env' module in package or '@system-env' globally
|
|
* - map targets support conditional interpolation ('./x': './x.#{|env}.js')
|
|
* - internal package map targets cannot use boolean conditionals
|
|
*
|
|
* Package Configuration Loading
|
|
*
|
|
* Not all packages may already have their configuration present in the System config
|
|
* For these cases, a list of packageConfigPaths can be provided, which when matched against
|
|
* a request, will first request a ".json" file by the package name to derive the package
|
|
* configuration from. This allows dynamic loading of non-predetermined code, a key use
|
|
* case in SystemJS.
|
|
*
|
|
* Example:
|
|
*
|
|
* SystemJS.packageConfigPaths = ['packages/test/package.json', 'packages/*.json'];
|
|
*
|
|
* // will first request 'packages/new-package/package.json' for the package config
|
|
* // before completing the package request to 'packages/new-package/path'
|
|
* SystemJS.import('packages/new-package/path');
|
|
*
|
|
* // will first request 'packages/test/package.json' before the main
|
|
* SystemJS.import('packages/test');
|
|
*
|
|
* When a package matches packageConfigPaths, it will always send a config request for
|
|
* the package configuration.
|
|
* The package name itself is taken to be the match up to and including the last wildcard
|
|
* or trailing slash.
|
|
* The most specific package config path will be used.
|
|
* Any existing package configurations for the package will deeply merge with the
|
|
* package config, with the existing package configurations taking preference.
|
|
* To opt-out of the package configuration request for a package that matches
|
|
* packageConfigPaths, use the { configured: true } package config option.

* Conditions Extension
|
|
*
|
|
* Allows a condition module to alter the resolution of an import via syntax:
|
|
*
|
|
* import $ from 'jquery/#{browser}';
|
|
*
|
|
* Will first load the module 'browser' via `SystemJS.import('browser')` and
|
|
* take the default export of that module.
|
|
* If the default export is not a string, an error is thrown.
|
|
*
|
|
* We then substitute the string into the require to get the conditional resolution
|
|
* enabling environment-specific variations like:
|
|
*
|
|
* import $ from 'jquery/ie'
|
|
* import $ from 'jquery/firefox'
|
|
* import $ from 'jquery/chrome'
|
|
* import $ from 'jquery/safari'
|
|
*
|
|
* It can be useful for a condition module to define multiple conditions.
|
|
* This can be done via the `|` modifier to specify an export member expression:
|
|
*
|
|
* import 'jquery/#{./browser.js|grade.version}'
|
|
*
|
|
* Where the `grade` export `version` member in the `browser.js` module is substituted.
|
|
*
|
|
*
|
|
* Boolean Conditionals
|
|
*
|
|
* For polyfill modules, that are used as imports but have no module value,
|
|
* a binary conditional allows a module not to be loaded at all if not needed:
|
|
*
|
|
* import 'es5-shim#?./conditions.js|needs-es5shim'
|
|
*
|
|
* These conditions can also be negated via:
|
|
*
|
|
* import 'es5-shim#?./conditions.js|~es6'

|
|
* load.metadata.deps and load.metadata.format will then be set
|
|
* for 'my/module'
|
|
*
|
|
* The same meta could be set with a my/module.js file containing:
|
|
*
|
|
* my/module.js
|
|
* "format amd";
|
|
* "deps[] jquery";
|
|
* "globals.some value"
|
|
* console.log('this is my/module');
|
|
*
|
|
* Configuration meta always takes preference to inline meta.
|
|
*
|
|
* Multiple matches in wildcards are supported and ammend the meta.
|
|
*
|
|
*
|
|
* The benefits of the function form is that paths are URL-normalized
|
|
* supporting say
|
|
*
|
|
* loader.meta({ './app': { format: 'cjs' } });
|
|
*
|
|
* Instead of needing to set against the absolute URL (https://site.com/app.js)

System bundles
